To all whom t may concern:

Be it known that EARL L. HOYLE and FRED D. Kms, citizens of the UnitedStates of America, residing at Hurley, in the county of Turner and Stateof South Dakota, have invented new and useful'Improvements in Oil Cans,of which the following is a specification.

The object of the invention is to provide an oil can of the forciblefeed or discharge type wherein the eiiicient operation of the dischargepump is not dependent upon a normal or upright position of the can butwherein the pump is adapted to function with the can either in a tiltedor inverted position; and with this object in view the inventionconsists in a construct-ion and combination of parts of which apreferred embodiment is shown in the accompanying drawin wherein Thegure represents a vertical sectional view of an oil can constructed inaccordance with the invention. f

The can 10 which may be of any suitable or preferred shape anddimensions adapted for the urpose for which it is designed is provided)with aspout 1l preferably clon# gated to correspond with thoseordinarily used by engineers, and at its inner end the spoutcommunicates by means of an elbow 12 with a pump cylinder 15 disposedlongitudinally of the can or in a position substantially perpendicularto the top and bottom thereof and extending substantially from theformer to the latter with its lower end fitted with a transverse inletarm 16 terminating in an upturned receiving nozzle 17. The can isprovided with the usual filling opening 18 having a removable cap orclosure 19 and fitted in the pump cylinder is a piston 20 having anoperating rod 21 upon which is coiled a spring 22serving to yieldinglyhold the piston or plunger in an elevated position or in the position atthe limit of the outward or suction stroke.

The spout is fitted `at its inner end preferably adjacent to the planeof the elbow 12 with an inwardly seating ball valve 23 held againstdisplacement to any material disf tance from its seat by a guard 24, andthe pump cylinder is provided below the point of communication of theelbow with the cylinder or between said spout elbow and the inlet elbow16 with a ported seat 25 for a ball valve 26 held against displacementby e guarl The inlet terminal or nozzle 17 of the pump cylinder isarranged within a conical chamber 28 to constitute a hood over saidnozzle which is adapted for the reception of oil from the body of thecan when the latter ,is tilted forwardly or inverted, to the end thepiston chamber of the cylinder 15 for y subsequent expulsion by aninward movement of the piston to force the outlet valve 23 from its seatand thereby permit outfiow through the spout.

Extending from the apex of the conical concentrating chamber 28 in whichthe inlet nozzle 17 is located, as above indicated, there is a vent tube29 which is provided with an outlet 30 near the top of the can. Thistube permits the escape of air from the chamber 28 when the can istilted to cause the oil to iow thereinto and prevent the formation ofanair pocket.``

In order that the ball valve 23 may be prevented from dropping from itsseat when the can is inverted, an expansion spring 23a is interposedbetween the ball and a guard 24. This spring alson prevents the pumpfrom drawing oil back from the spout through the valve 23, as would bethe case p cylinder and the spout, anda hood overhanging the said inletnozzle and forming a chamber at kthe front or nozzle side of the caninto which said nozzle upwardly projects, a vent tube being extendedfrom the upper end of said chamber to a point near the top of the can.

2. An oil can having an outlet spout, a pumping mechanism having itscylinder in communication 'with the inner end of Saad F' let Valveslocated respectively in the pumpY cylinder and the spout, a hoodoverhanging the said inlet nozzle and forming a chamber at the front ornozzle side of the can, said nozzle projecting upwardly into saidchamber, `and a vent" tube extending" 10 diagonally of the can andcommunicating at one end with the upper end of said chamber, Said Venttube terminating at the top of the can adjacent said pump cylinder.

In testimony whereof they aliix their signatures.

EARL L. HOYLE. FRED D. KIES.
